APPARATUS FUR Application August In Germany '3 Claims. (01!. 71-4) Inthe chambers shown in Figs; 1-3, the sta- This invention relates toapparatus for the manufacture of superphosphate and the like products.

The chief cause of =the defects of the superphosphate reaction chambershitherto generally employed, resides in the intermittent manner in whichthey operate.

The present invention aims at providing reaction chambers which areadapted to enable the my work to be carried on continuously, in that thereaction mass and the support on which it rests and adheres is moved inrelation to that part of the chamber which contains the intake (mixingmachine) and the discharge device, so that the dissociated portions ofthe charge canbe conveyed continuously to the discharging device andfresh raw'material can be fed into the vacant portion of the chamber.

In-the embodiments illustrated in the accomgg panying drawing, theseparts rotate on a horizontal axis.

As the apparatus rotates on a horizontal axis, the stationary hollowcylinder b prevents the liquid superphosphate from spreading towards Thedrum 0 and reaction mass rotate on the horizontal rotational axisy--@:-and

accordingly, the mixer 'm and discharging device I of the knife thelatter "material and detaches dislodged material falls through arestationary whilst the other parts and walls can be connected either tothe stationary or the 3p rotary systems, as may be most convenient. Thehollow cylinder is providedwith ,an opening of ample dimensions,extending from near the one end wall a to the other end wall a and fromthe auxiliary wall a to about a line under the knives 5 14. Through thisopening the dislodged material passes into the hollow cylinder, fromwhich it is led into the open by means of any convenient conveyor. Theauxiliary wall a is connected with the hollow cylinder and merely servesas a boun- 449 dary for the dissociation chamber, so that the gasesliberated by the dissociation process can be evacuated.

In order to make clear the character of my invention, a preferredembodiment is illustrated in the drawing wherein:

February 2!, 1929 of an end wall a in which is placed a hollow cylinderb, concentric with the rotational axis. The end wall a (in which is sunkthe mixer m) and the hollow cylinder in are held in place by an ironstructure. The opposite end wall a is connected with the cylindricalshell 0, with which it turns in the direction of the arrow s. Thecylinder, which is mounted on rollers r,

is driven, in the usual manner, by a pinion '1 with driving wheel 2 Thecontact surfaces between I a, and c, and also between'a and b, are selftightening. The auxiliary wall a is disposed vertically and tangentiallyin relation to the hollow cylinder b. It carries the exhaust gas flue l,which passes out of the chamber through a and is connected with a fan.The discharging device consists of the knife 14,

which is disposed at right angles to the rotational axis and isreciprocated in the direction of the double arrow s", by means of theguide rods 15 which slide in the bearing 16 and are moved by a crank orthe like. a is provided with a slot through which the knife 14 passesout of the interior of the chamber and is thus detached from the blockof material. While the knife is in this position the cylinder 0 is movedforward so that, in the next forward movement encounters a thin layer ofit from the block. The

The surfaces of contact with the cylinders c are closefitting. The cylinders c are mounted on rollers r, and are uniformlymoved by means of the toothed crowns z. The discharging device consistsof a number of knives 14, which are attached to two endless chains 17.

These chains, together with the knives, are moved' by a toothed wheelnot illustrated in the direction of the arrow s pass out of the chamberthrough a slot in a, are diverted from this direction of movement byrollers not shown and passed round the outside of the chamber, to be ledover other rollers and into the chamber again through a slot in (1 Thisarrangement of the discharging device enables the two cylinders c to bemoved in a uniform manner. The dislodged material drops through theopening provided in the hollow cylinder b and on to the conveyor 23.

Instead of being vertically disposed, as shown, the knives may also bearranged parallel with the rotational axis yy. The embodiment shown inFigs. 1-3 would be provided with a knife, clamped on one side in asliding shoe and swinging up and down in a guide track provided in a. Inthe ex-.

ample shown in Fig. 5, a number of knives, attached to two endlesschains, would be provided. These chains would run at right angles to therotational axis and guided, in each case, by two rollers mounted in theend walls a and a respectively.

In the embodiment according to Fig. 5, the

parts a, c and a as a whole, assume approximately a spherical form. Theend wall a is connected to the stationary hollow cylinder b, and

carries the mixer m. a and c constitute a unit,,

are mounted on rollers 1', and are rotated by means of the toothed crownz. The block is broken down by'means of the knife 14 which rocks on theshaft 13 driven by a crank or the like. The reaction mass is movedforward intermittently, and at the moment when the knife 14 is insidethe cylinder 1). .The dislodged material is carried away by the conveyor23. The contact surfaces between a and c, and between a and b, areself-tightening. Z is the gas exhaust flue.

The reaction chamber shown in Fig. 6 is in the form of a ring ofcircular cross section. The stationary cylinder is connected to the endwall a, and the rotary support 0 is connected to the end wall a Theblock is broken down by means of a revolving knife disc 14, driven bythe pair of pinions 7c and :i. The toothed crown 2 serves to drive thesupport 0, and the conveyor 23 to remove the dislodged material. I isthe gas .exhaust flue.
